ventional frictionmaterial. `Aheavy reinforced y My invention relates toimprovements in car brakes for railroad cars of all kinds. 1

The main object is to provide a manually controlled brakingV means for'use in connection and addition, to the "usual air brake equipment andwhich is'so arranged that it may be operated and set'without climbing tothe top of the car to the lhandwheel locatedthere as is the case atpresent.

"Another object isto provide abrake in'which the action is positive andincreases with the strain -'against it and which is connectedpositivelyto the air brake equipment without complicated mechanism liable tobreakage.

Another object is to provide a'brake which may be setbyra hand leverorfoot pedal both conveniently located for operation from the ground orr'lower' step at the side of the car. A further object is to provide :abrake of this -kind in a simple, practical and durable form comprisinga' brake or friction icone wheel mounted 'on the car truck axle and amating wheel mounted 'ona shaft Vsupported'alongsider the axlein aAbracket secured Yto the truck, .said shaft being `slidable axiallythrough the bracket under control 'of aremote hand lever or foot pedalto bring the cone wheels into engagement and the shaftlbeing restrictedagainst rotation by a chain fastened to it and running to the servicecylinder `or suitable part of the air brake equipment...

Withthese and other objects in view the Vin-v :vention resides in thenovel construction and arrangement .of parts asr hereinafter fully setforth and claimed,v reference being `had to the accompanying drawingswherein: v

' Figure 1 is a plan view-of a conventional form of railroadcar truckequipped with my brake, the brake being shown in disengaged position..Figure2 is a side; elevation of the structure `shcflwn-inlFigure 1; Y

Figure 3 is an enlarged plan view of the brake zalone, the controlshaft, pedal and lever being` omitted. Figure 4 is a sectional viewalong the line 4 -4 in Figure 3. Figure 5 is an enlargedsection alongthe line 5-5 in Figure 1. e Y f Figure 6 is a diagrammatic plan viewofthe brake as applied to a-car truck and connected to lthe air brakeAequipment, the brake operating means and its connecting chain beingshown in full lines and the remaining structure in broken lines.

Referring now with more particularity to the drawings a conventionalform `of a railroadvcar truck is represented atA comprisingthe sideframemembers B andcentral cross beam C,v the axles D and wheels E. VInaccordance with my invention a cone or tapered brake or friction Wheel'I is secured on one axle D adjacent one end thereof and made of somedense and hard conbracke't 8 is mountedon the cross beamy C by vbolts 9and includes spaced parallel bearing arms vIll and-II extended laterallyfrom the beam out toward the axle D carrying the brake wheel'I andinwardly thereof, said arms terminating vin bearings I2 havingconventional lubricating means as-usually employed in suchinstallations.

A brake shaft I3 is slidably and rotatably mounted through thesebearings I2 parallel with the axle` E and at its outer end a conical ortapered brake lor friction .wheelV Ill is rigidly aixed, Ythis wheelbeing `also of suitable 4friction material.

It will be noted that the two brake twheels I and I4 taperoppositely,that is, as'herefshown the wheel l on the axle tapersoutwardlywhile Ythe other I4 taperslinwardlyand it will be readilyunderstood'that by shifting or sliding the brake shaft I3 inwardly thecomplementary angular duce `wear thereon.

A shifting fork orl lever I9v is fulcrumed inter'- mediate its ends' atVZIJ onabearing ear 20a extended from the bearing arm II. and; is forkedat one end 2l to embrace and freely receive'the brake shaft I 3justfoutwardly of the collar, I'I, this forked end playing between thiscollar and another A22 spaced outwardly therefroml as shown.v

VAn operating shaft 23 is journaled in bearings 24 alongand within onetruck frame side .member B in the cleft or space B usually found betweenthis n'ieniberv and the adjacent wheel E,said shaft extending fromV apoint 4adjacent the cross beam C out endwise from the'truck Aa suiicientdistance to reach` toand slightly project `beyond the end of the car (Fin Figure 6) beneath which the truck is mounted. `A radially extendedarm or finger 25 is provided near the inner end of this operating'shaftl23 and is connectedby a cable-or chain' 2B to the free end 21 'of thefork I9. A hand lever 28 is secured'at 29 to the operating shaft nearits outer end and in such position as to clear the end of the car and afoot pedal 30 is secured-at (il tothe shaft inwardly of the lever and isarranged to project laterally from the car. adjacent theusual steps orladder (noti shown) thereon; Inwardly of the foot pedal y 30 a ratchetwheel v32 is secured'to theope'rating shaft 23 and a locking lever orlatch 33'is fulinner end adapted to engage this ratchet Wheel. Theopposite outer end 31 of the latch extends laterally outward from thetruck for convenience in operation. The latch maybe spring set by atorsional spring 33a to normally engage the ratchet wheel 32 if desired.

The brake operating means as so far described is adapted for connectionto and operation with" `the usual air brake equipment as representeddiagrammatically in Figure 6in `which Fas aforesaid designates therailroad'car only one* end of which is shown and G designates the airbrake service cylinder, H the hand brake lever, I the usual brake shoesoperated by either the hand wheel J or by the air brake pull rod K. Thisis conventional equipment or one form thereof and'y V is shown merely`ferpurpose of exeinpli'catipn,

itbeinglunderstood that the present invention may tbe' connected 'to anystandard .air brake sys'-V tion: the chain leading 4from theviever 'HtctheV shaft J is disconnected from the latter-.and anotherchain 3% (orthesame chainappropriately altered) is extended from the lever overapulley 39 secured on the cross beamC and is then -fastened -at zits'end4U to thebr-ake'shaft I3 between the'bearings |21 as shown. 1 -f V Inuse either'the hand lever 28 vor the foot pedal 30-may bepulled outwardor pushed'downward respectively, Yeither operation rotating the shaft23so-.as t pull on the cable 26 ,and swing the shifter fork i9 onitsbearingtl;V :The fork k2| thus moves the brake shaft ,l 3.axiallythrough the bearings n vI 2 bringing ythe brake wheel .i4 into Ycontactwith the wheel l*l--on theV truck axle 2D. The' car being in motion bothwheels l and vrl# will thus be rotated and thek brake shaft i3 will turnwinding the `chain y3B on the axle and exerting a .strain on theVhandbrake lever H so that the brakeishoes-I will beset and the wheels Elockedfstopping the can, Uponlmoving the hand lever2f8'orpedal Bllin theopposite direction or releasing -themfby rst releasing latch 33 thespring i8 will 'disengage the wheelsjl and 1,4 releasing thebrakes aswill-bexapparent. The braking action ior force increases 'directly asthevstrain* against it sinceit ist-he' rolling action of .the car itselfthat sets'the brakes rather than simply 'ma-'n power as is the case inprevious arrangements nowin use. The -brake operating means ofcourse-'workstwith equal Veiliciency on movement ofthe :car in eitherdirection and when not in use does not interfere in any way with the'VnperationV of .the air brake equipment., ."I'fhe hand 4lever28 isconveniently 4operated by a man lon the 'groundor roadbed at the end ofthe car .while the foot pedal 30' is placed in positionfor operationbyaman standing on the usual 'step jor ladder at the side of the car,neither operation requiring that the operator climb clear to the carthelatch as willbeievident. Cars may thus be fspotte'd locked in.positionV orslowed vdown gradually as needed simply byrpropermanipulation nf'thecntrol levenpedal and latch as will 'be readilyapparent; x f

It will be noted that the arms I and Il of the bracket 8 extend downwardat Illa and Il a and are bolted at 9a alongside the cross beam C to apoint substantially levelof the axle .D before extending outwardasdescribed, this` formation increasing the strength of the bracket aswell as properly supporting the brake elements carried thereby.

While I have herein set forth a certain preferred embodimentv of myinvention, it is understood that I may vary from the same in minorYstructural details, so as best to construct a practical Adevice fnr thepurpose intended, not departing from the spirit of the invention andwithin the scope of the appended claims.
